Quality Control

Our 1,3-Benzenediol, 4-[(1S)-1-Hydroxyethyl]- (9Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for pharmaceutical and advanced synthetic applications. A Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles is provided with every shipment. We support compliance with cGMP and ISO guidelines for critical raw materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
